UNIVERSAL PLUMIB.

Specification of-Iietters Patent.

Patented June 3, 1913.

Application filed October 28, 1912. Serial No. 728,040.

To all whom it may concern:

Be it known that I, GUsTAr ADoLr SKooe, a citizen of the United Statesof America, residing at Youngstown, in the county of Mahoning and Stateof Ohio, haveinvented certain new and useful Improvements in UniversalPlumbs, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to universal plumbs especially designed for bricklayers, masons, carpenters and other artisans.

The objects of my invention are to pr0- vide: First, an instrument ofprecision embo-dying positive and reliable means, as hereinafter setforth, for facilitating the construction of walls, columns and otherstructures. Second, a plumb that can be located upon one of the cornersof a column whereby the other corners of a column can be accuratelyascertained. Third, a plumb embodying means whereby lines can be accurately stretched and supported for the laying of a wall or anyprojections thereof. Fourth, an instrument that serves as a spacingdevice to obtain accuracy in spacing courses of bricks or other materialto be laid. Fifth, an instrument that obviates the necessity ofconstructing several courses at the corners of walls in order to obtainguide lines for the construction of the remainder of the walls, theinstrument permitting of,

corners and side walls being simultaneously constructed. Sixth, aninstrument of the above type that is simple in construction, easy toadjust and inst-all and highly efficient for facilitating the work ofartisans.

My invention further aims to accomplish the above results by amechanical construction that will be hereinafter specifically describedand then claimed, and reference will now be had to the drawings, whereinFigure 1 is a plan of a portion of the instrument, Fig. 2 is a frontelevation of the same, Fig. 3 is a side elevation of the instrument,Fig. 4. is a perspective view of a detached se ment, Fig. 5 is aperspective view of a detached bearing, Fig. 6 is a plan of a detachedline holder, Fig. 7 is a cross sectional view of the same, and Fig. 8 isa plan of a detached clamp.

Further describing my invention in detail with reference to thedrawings, wherein like numerals denote corresponding parts throughout 1denotes a tubular upright and mounted upon the lower ends of said.

upright by transverse pins 2 are the split sleeves 3 of clamping members4, these mem bers being located one above the other. The members areclamped upon the corner of column or wall by adjustable screws 5 havingthe heads 6 thereof provided with shiftable handles 7. The clampingmembers 4 have angularly disposed arms 8 reinforced by ribs 9 andprovided with yieldable con:

tact pads 10. The arms 8 are at right angles f to one another and can beeasily clamped upon the corner of a column or walls with out any dangerof the side arms injuring the bricks or material to which they areconnected.

11 denotes a T slidably mounted upon the upright 1, above the clampingmembers, and adjustably held thereon by a set screw 12. Adjustablymounted in the T 11 by a set screw 13 is the stem 14 of a V-shaped lineholder 15, said line holder having right angularly disposed notched armsto which one or more lines (not shown) can be easily and quicklyattached. The line holder presents a V-shaped notch 16 that cooperateswith a plumb bob, to be hereinafter referred to. I

17 denotes a T mounted in the upper end of the upright and provided witha set screw 18 for adjustably holding a cylindrical or tubular beam 19positioned at right angles to said upright.

20 denotes a bearing slidably mounted upon the beam and adjustably heldthereon by a set screw 21. The bearing is provided with a depending hook22 and suspended from said hook is a plumb bob 23. adapted to verticallyaline with the notch 16 to determine the vertical outer edge of thecorner of walls or a column to be constructed that has the outer edgesthereof determined by lines held by the holder 15. The bearing 20 has astud 24 and swiveled upon said stud by a screw bolt 25 are the aperturedinner ends of tubular angularly disposed arms 26. Adjustably mountedupon. said arms by set screws 27 are sleeves 28 for depending hooks 29provided with plumb bobs 30.

31 denotes a segment secured to the bearing 20 by ascrew 32 or otherfastening means, said segment being also secured to asupporting blockresting on the beam 19 by a screw 33 or other fastening means. Thesegment has segment slots 34 and levels 35 and 36 to determine when thesegment and the beam 19 are level relatively to a piece of work.

37 denotes supports for the arms 26, said supports having shanks 38extending into the slots 34 for guiding a movement of said supports thatrest upon the segment 31.

39 denotes a sleeve adjustably mounted upon the beam 19 by a set screw40, said sleeve having a depending hook 41 provided with a plumb 42.

The instrument as above set forth can be easily clamped on the cornersof'walls and in case of any obstruction inside the wall interfering withthe beam 19, said beam can be Withdrawn so that it does not extendinside the wall. In this instance the arms 26 and the segment areremoved and simply the plumb, bob 42 employed to locate the line holder.The plumb bob 42 cooperates with I the plumb'bobs 30 and 23 in locatingthe fourcor'ners of a column, the instrument being fastened to onecorner of the column, the plumb bob 23 locating the corner to which'theinstrument is attached, the plumb bob 4L2 locating the corner oppositethat located by the plumb bob 23, and the plumb bobs 3O locating theother corners of the column.

From the foregoing it will be observed that the instrument has atwo-fold purpose. F irst, that of serving as a support for one or morelines used as a guide for laying a Wall or projections thereof. Second,as a spacing device to obtain accuracy in spacing courses, which isaccomplished by raising the line holder upon the upright a predetermineddistance to bring the line or lines to a level required for a course ofbricks or stones. The adjustable arms 26 are'only used when constructingcolumns whereby the location of four corners at once is desired, or onwalls whereby the corner is greater or less than 90 degrees. In cases oflong walls other means than the clamping members can be resorted to forsupporting the instrument and provision can. be

made for intermediate supports for long lines between corners.

While in the drawings there is illustrated a preferred embodiment of myinvention, it is to be understood that the structural ele ments aresusceptible to such variations and modifications as fall within thescope of the appended claims.

What I claim is 1. An instrument of the type described comprising anupright, clamping members adapted to support said upright, a V-shapednotched line holder adjustably mounted upon said upright, a beamadjustably sup ported by the upper end of said upright at right anglesthereto, a bearing adjustably mounted upon said beam, a sleeveadjustably mounted upon said beam, plumb bobs supported by said sleeveand said bearing, arms supported by said bearing, and plumb bobsadjustably supported by said arms.
